"I believe that it is critically important to carefully review each person's individual situation so that we can provide the care that will give the best chance of having a healthy baby. Although I provide clear recommendations about evaluation and treatment, I feel that it is also very important to provide information about choices so that people can have input into making the decisions that are right for them."
